The rectangle below has an area of x^2-15xy+56y^2 square meters and a width of x-8y meters. what expression represents the length of the rectangle?

We need a length such that

We deduce that

and we may solve the problem using long division. Nevertheless, it's rather simple to deduce that the length also has to be a linear polynomial in and , and thus something like .

So, we have

And finally, we have

if and only if the coefficients of the terms are the same. So, we want

Since is given, it's easy to see that the solutions is

So, the length is

In fact, we can check

the distance from any point on the parabola to the focus is the exact same as the distance from that point to the directrix.

if you could provide answer choices that might allow me to answer the question easier if my above answer isn't an option! (:

answer: $34.31

step-by-step explanation:

$11.99 x 3 = $35.97

$35.97 - 10% = $32.37

$32.37 + 6% = $34.31
